Caluxe C55 Tart Wax | Calwax Tart Wax for Melts - Slab Form

• This wax is much harder than our container waxes.  Personally, I use a butter knife to cut it into more manageable pieces. 
• Heat to 190 - 200° F, remove from the heat source, add fragrance oil, stir for 60 seconds and pour depending on the material that you're pouring into.  For silicone molds, pour around 170 - 180°F.  For clamshells, pour between 145 - 170° F. Please see your clamshell vendor's product description for exact pouring temperature.  
• For the smoothest tops on clamshells or larger melts, pour 85% of the container, cool, then pour the remaining 15%.
• The maximum fragrance load is 8-10%, but higher fragrance loads should be tested per fragrance.
• We recommend allowing a 1 week cure time to maximize the cold and heat throw.

Safety Data Sheet

How do you calculate the amount of fragrance oil to use?

First, you need to know what percentage of fragrance oil you want to use. The average usage is 6%.

Here is a basic formula:

(oz of wax using) x (% of fragrance oil you want to use) = (oz of fragrance oil needed)

For example, let's say you are using two pounds of wax and want to use 6% fragrance oil.

First, you'll need to calculate the number of ounces of wax you have:

2 x 16 (number of oz in 1 pound) = 32oz

Plug these numbers into your formula:

32 x 6% = 1.92oz

You can round up to 2oz for easy measuring on your scale.

Below, I created an easy fragrance load calculator where it will calculate the amount of fragrance oil needed in both ounces and grams.
